The internal resistance of a liquid to flow is known as
The Right Option here is (B)
Internal Resistance of Liquid
The magnitude of internal resistance or friction in a fluid which is measured by the force per unit area resisting the uniform flow is commonly known as Viscosity.
What is Viscosity?
Other terms of viscosity are dynamic viscosity, absolute viscosity, or simple viscosity. In simple words, it is defined as internal resistance or friction present in a fluid.
Symbol of Viscosity
It is represented by the Greek letter η (eta).
Unit of Viscosity:
The SI unit of viscosity is the pascal second [Pa s]. The Gaussian unit of viscosity is the poise [P = dyne s/cm2]. While Ten poise equal one pascal second [10 P = 1 Pa s].
Factors Affecting Viscosity
-
- Viscosity varies with the material. (Viscosity is a property of materials.)
- The viscosity of simple liquids…
- decreases with increasing temperature
- increases under very high pressures.
- The viscosity of gases…
- increases with increasing temperature
- is independent of pressure and density.
